I haven't figured mine out after ten years. I just put it on the snowflake and set the fan to the icon that looks like a volume control going up and down. There are other clues I could give you but it would spoil the fun of trying to figure out who on earth designed the "human" interface.

I had the same issue with my new Daikin aircon, online manual only available in Thai. I emailed them asking for an English version. My email was passed from Customer Service department to their Enginnering department where it was passed between a couple engineers. Within 2 days one of the engineers emailed me an English version of the manual, excellent service !
